The mercenary was employed by the South Koreans to rescue an important figure in the South Korean government that was held prisoner by the Chinese in Pyongyang Airport, which was heavily guarded. The mercenary (and some escorts) headed to the airport in a vehicle and crossed into the Chinese quarrantined side to rescue the prisoner, after checking three hangars. The target was taken, and the South Koreans fled the airport to Kaesong with their man. He was returned, and the relationships between South Korea and China drastically broke down.
